Why This Matters

Positive psychology isn't just about "thinking happy thoughts"—it's a rigorous scientific framework for understanding what makes life worth living. In GENED 1025, you're being tested on your ability to distinguish between different pathways to well-being: intrinsic vs. extrinsic motivation, hedonic vs. eudaimonic happiness, and individual vs. relational flourishing. These theories form the backbone of the course because they offer competing (and sometimes complementary) answers to the central question: what actually makes people happy, and why?

The theories below aren't isolated ideas—they connect to each other in meaningful ways. Seligman's work evolved from Authentic Happiness to PERMA. Self-Determination Theory explains why flow states feel so good. Mindfulness practices enhance the gratitude that Broaden-and-Build says we need. Don't just memorize definitions—know what psychological mechanism each theory emphasizes and how it relates to the others. That's what separates a strong exam response from a mediocre one.


Motivation and Basic Needs

These theories focus on what drives human behavior and the psychological conditions necessary for flourishing. The core insight: sustainable happiness comes from within, not from external rewards.

Self-Determination Theory

  • Three basic psychological needs—autonomy, competence, and relatedness—must be satisfied for well-being to flourish
  • Intrinsic motivation (doing something because it's inherently rewarding) produces more sustainable happiness than external rewards like money or praise
  • Autonomy support from environments and relationships predicts greater life satisfaction and personal growth

Growth Mindset Theory

  • Believing abilities can be developed through effort and learning leads to greater achievement and resilience
  • Embracing challenges rather than avoiding them fosters a love of learning and self-improvement
  • Reframing failure as opportunity for growth is linked to higher life satisfaction and persistence

Learned Optimism

  • Explanatory style—how you interpret setbacks—can be deliberately shifted from pessimistic to optimistic patterns
  • Cognitive reframing involves challenging automatic negative thoughts and replacing them with constructive alternatives
  • Resilience in adversity improves measurably when individuals learn to dispute catastrophic thinking

Compare: Self-Determination Theory vs. Growth Mindset—both emphasize internal drivers of success, but SDT focuses on environmental conditions (autonomy, competence, relatedness) while Growth Mindset focuses on individual beliefs about ability. If asked about motivation in relationships, go with SDT; for academic or achievement contexts, Growth Mindset is your stronger example.


States of Engagement and Presence

These theories examine how we experience the present moment and why certain activities feel deeply satisfying. The mechanism: full attention creates optimal psychological states.

Flow Theory

  • Complete immersion in an activity occurs when challenge level precisely matches skill level, creating optimal experience
  • Loss of self-consciousness and time distortion are hallmarks of the flow state—you forget yourself and hours feel like minutes
  • Autotelic experiences (activities done for their own sake) contribute to long-term life satisfaction and personal fulfillment

Mindfulness-Based Stress Reduction

  • Present-moment awareness without judgment reduces stress and enhances emotional regulation
  • Observing thoughts and feelings rather than reacting to them fosters clarity and psychological flexibility
  • Systematic practice (meditation, body scans) is linked to measurable improvements in mental health outcomes

Compare: Flow vs. Mindfulness—both involve intense present-moment focus, but flow requires active engagement with a challenging task, while mindfulness cultivates receptive awareness of whatever arises. Flow is about doing; mindfulness is about being. Both reduce rumination, but through different mechanisms.


Positive Emotions and Cognitive Patterns

These theories explore how positive mental states build resources over time. The key insight: positive emotions aren't just pleasant—they're functionally useful for survival and growth.

Broaden-and-Build Theory

  • Positive emotions expand cognition—joy, interest, and contentment broaden your thought-action repertoire, encouraging creativity and exploration
  • Resource accumulation occurs over time as positive experiences build social connections, intellectual skills, and physical health
  • Upward spirals develop when broadened thinking leads to more positive emotions, which further broaden thinking

Gratitude Theory

  • Recognizing and appreciating positives enhances emotional well-being and shifts attention from scarcity to abundance
  • Regular gratitude practice correlates with reduced depression, increased happiness, and stronger social bonds
  • Savoring what you have rather than focusing on what's missing fosters a sustainable positive mindset

Compare: Broaden-and-Build vs. Gratitude Theory—Broaden-and-Build explains the mechanism (positive emotions expand thinking), while Gratitude Theory identifies a specific practice that generates those emotions. Think of gratitude as one reliable way to trigger the broaden-and-build process.


Comprehensive Well-Being Frameworks

These theories attempt to capture the full picture of human flourishing—not just feeling good, but living well. They integrate multiple components into unified models.

Authentic Happiness Theory

  • Alignment between values and actions produces genuine happiness—living according to what you truly believe matters
  • Three pathways to happiness: positive emotions (the pleasant life), engagement (the engaged life), and meaning (the meaningful life)
  • Strengths-based living encourages pursuing activities that leverage your natural talents and virtues

PERMA Model

  • Five pillars of well-being: Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment—each independently contributes to flourishing
  • Holistic framework evolved from Authentic Happiness Theory, adding Relationships and Accomplishment as distinct elements
  • Actionable cultivation of each domain enhances overall quality of life—you can deliberately build each pillar

Character Strengths and Virtues

  • 24 character strengths organized under six universal virtues (wisdom, courage, humanity, justice, temperance, transcendence) provide a taxonomy of positive traits
  • Signature strengths—your top 3-5 strengths—are most energizing and authentic to deploy in daily life
  • Strengths-based interventions (using signature strengths in new ways) produce lasting increases in happiness and life satisfaction

Compare: Authentic Happiness vs. PERMA—both are Seligman's frameworks, but PERMA is the evolution. Authentic Happiness emphasized three lives (pleasant, engaged, meaningful); PERMA adds Relationships and Accomplishment as independent contributors to well-being. Know this progression—it shows how the field's understanding deepened.

Self-Check Questions

  1. Which two theories both emphasize present-moment awareness but differ in whether the person is actively engaged versus receptively observing? What's the key distinction?

  2. How did Seligman's framework evolve from Authentic Happiness Theory to the PERMA Model? What elements were added, and why might they matter independently?

  3. Compare Self-Determination Theory and Growth Mindset: both address motivation, but one focuses on environmental conditions and the other on individual beliefs. Which would you use to explain why a supportive mentor increases well-being?

  4. If an essay prompt asks you to explain how positive emotions contribute to long-term resilience (not just momentary pleasure), which theory provides the strongest mechanistic explanation? What's the mechanism?

  5. Gratitude practice, identifying signature strengths, and cognitive reframing are all interventions. Match each to its parent theory and explain what psychological process each targets.
